I like seeing an in-depth review. These days it feels like all the major sites rush out the reviews right before launch day with less than a day of actually testing being done. The reviews often sound like just a re-hash of the press release specs.
Now that an 800mhz A5 gets better scores than 1.2Ghz chips... are we going back to the PPC vs Intel days?

As others have said, unless you're only changing one element in the hardware/software stack, it's not an apples-to-apples comparison. However, A5 is reported to use out-of-order execution, whereas A4 and earlier iPhone CPUs are purely in-order. Integer ALU pipeline length has reportedly also been reduced. The memory bus clock has also been doubled. All else being equal, a single A5 core should therefore beat the A4 o…
It is indeed a SMP core (1-4 CPUs), which does out of order execution and register renaming. And it outperforms the Cortex-A8 (an in-order CPU) on a per-clock basis on many workloads.
But it's not an Apple part. Everyone is shipping these things now.

Anandtech does awesome in-depth reviews but most of the stuff they are talking about is not relevant to the average consumer in the slightest. If other sites were all doing that many would not be relevant to their readers interests.
I think Brian Lam's Wirecutter[0] takes a step in the right direction. Gdgt[1], which has been around for a while, seems interesting, too, as it's user-generated content, so the experiences rendered are those of self-chosen peers.
P.S. For some reasons, I always read your username as the first word of the comment, so it always sounds in my head like you're saying, "Ugh, Anandtech does awesome..." In my head, you're quite an irritable fellow. There's someone else named "yawn" who always seems bored.

A DRAM package is then stacked on top of the SoC. Avoiding having to route high-speed DRAM lines on the PCB itself not only saves space but it further reduces memory latency.
Uh... come again? DRAM latency is a function of the analog circuit inside the chip, not the wires you connect to it. At best, you might be able to drive the chips at a higher transfer frequency (but even then, the limit is probably on-package in the DRAM, not due to board trace problems). But that has at best a minimal effect on latency (you're shrinking the handful of transfer cycles at the end of the read).
The advantage of the PoP configuration is precisely that it saves space -- quite a bit of space, and it's a great trick. But this bit is just way off.

I, as I assume most on this site, only considers Anandtech the one true tech product reviewer on the web. The only other equal is John Siracusa's review of the latest Mac OS release.
